Bikesharing has evolved greatly since the first program was launched in the Netherlands in the mid-1960s. As of May 2011, there were an estimated 136 bikesharing programs in 165 cities around the world, with 237,000 bikes on the streets. In the Americas, bikesharing activity has spread to Canada, Mexico, the US, Argentina, Brazil, and Chile. Asia, which represents the fastest-growing bikesharing market today, has programs in China, South Korea, and Taiwan.
